What These Updates Cover

Each note is written to explain the player-facing result first, then the design or technical reason behind it. This keeps the update history useful for returning mayors, new players, and search crawlers reading the site without launching the game.

City Systems

Road access, utility coverage, zoning behavior, taxes, happiness, public services, and the rules that shape city growth.

Performance Work

Model loading, render cost, cache behavior, and mobile-friendly changes that keep the city playable on modest devices.

Player Guidance

Short explanations of how each change affects city planning, budgets, service placement, and early-game decisions.

Community Feedback

Comment threads collect bug reports, balance reactions, and requests so follow-up work can be tied to a specific version.

How To Read A BuildCity Patch Note

The update log is organized around practical questions a player would ask after returning to a saved city.

Check the gameplay impact

Look for changes to money flow, service coverage, roads, zoning, happiness, and city rank before changing a long-running layout.

Review stability notes

Performance, loading, cache, and save-state fixes are called out because they affect browser memory, network requests, and older devices.

Use comments for follow-up

If an update changes your city in an unexpected way, leave feedback on that version so the report includes the right context.

Version v1.1.0

Major rendering performance improvements. Clouds, data-view bars, and fireworks are now instanced, with anti-aliasing tuning and memory-leak fixes for steadier frame rates in long sessions.
The Tourism Bureau now unlocks at Small City (1,000 population) instead of City (5,000).
Trade gift claims are now safe. If the receiving city has no matching resource warehouse, the gift stays unclaimed instead of being lost — build a matching warehouse, then claim it.
Public building unlock requirements (city rank, departments, prerequisite buildings, Tourism Bureau level, etc.) are now also validated on the server, blocking modified clients from placing locked buildings.
Daily quest happiness goals now accurately reflect your city's actual happiness.
Better guidance when the verification email doesn't arrive: the sending address is shown, spam-folder hints and a resend cooldown were added, and school/work email filtering is explained.
Added a shortcut to the shop when you run out of gems, and you now receive 50 gems for reporting a bug.
Improved home/ranking loading speed and server stability.
